12 Claims. (01. 91-25) This invention relates to novel and useful im- 1 proveinents in apparatus forapplying liquid ma:

terial to surfaces such as inthe formation ofof the chassis, constantly vibrate the hopper carrier and hopper in a direction parallel to the path of travel of the chassis, valve the hopper by manual means at the discretion of the opera tor of the device, andconstantly reciprocate a brush forwardly of the egress portion of the hopper.

'Another object of this invention is to conveniently locate the control for a heater which is attached to the hopper carrier, and the motor switch on a handle which is used for the pur-I poses of propelling the device and also for opening and closing the valve. I

The present invention has been developedto incorporate various structural features of ad vantage over devices known in the art. By the utility of the structural features referred to the" application of asphalt and other substances on floors, roofs, etc., become relatively easy. It is one of the prime purposes of the invention to render theworkmens task lighter and to perform a better application of a coat of such material on asurface. l p

The instant surface conditioner applies an even coat of material to the surface to be treated,

after it has been acted upon by the bush mounted rearwardly of the vehicle. The amount of actual conditioner spread on the surface is selectively regulated by the operator of the device by mere manipulation ofthe same handle which he utilizes to propel the device.

Other structural and operational advantages will become apparent in viewing the drawings. Noting Figure 2 it will be seen that a chassis is illustrated which includes two sections ill! and I2 respectivelyconnected together by means of a hinge generally indicated at 14. This: hinge has two sections 16 and I8 in the makeup thereof with a spring 20 reacting on each hinge section and ultimately on the sections [0 and 12 of the chassis.

It is seen that the hinge is so constructed as to allow bending or flexing of the entire chassis to raise and lower the forward end having thewheel 22 mounted thereon and the rear end having the wheels 26 and 28 respectively carried thereby.

A supportwhich includes a front plate 30 and a rear plate 32 is attached to the section ID by" any suitableconventional means and carriesa shaft 34 at the upper ends of said plates. This shaft has a handle 36 rigidly secured thereto 3 whereupon rotation ofthe handle produces corresponding rotation of the shaft 34. The function of the handle is threefold. It is used as a supportfor a heater control switch or rheostat-switch 38, a motor switch 40; it is used as an operating means for propulsion of the vehicle; and it is used for the purpose of imparting rotation to the sheave 42, alternatelycontrolling the actuation of a valve mechanism. 3

A brackettype support 44 which is substantially U-shaped is attached at the web thereof to the plate 32 projecting rearwardly ofthe device.

FICE,

This support maintains a hopper carrier having side walls, a rear wall 48 and a front wall 46. The supporting takes place through the utility of horizontal pivot pins 50 whereby the hop per carrier and hopper 52 mounted therein are mounted for pivotal movement about the pivot pins 50 as an axis so that the hopper bottom swings in a direction generally the same as the travel of the vehicle chassis.

Means for oscillating the carrier in very short strokes so that vibratory movement occurs is provided. The preferable means consists of a motor 54 which is mounted on the section It of the chassis and which has a drive shaft 56 depending therefrom and through the said section III. This shaft has a pulley 58 attached thereto with a belt GI] entrained therearound. This belt also extends around a second pulley 62 which is mounted on a pin 34. The said pin (see Figure 8) is journalled in a bearing 66, which is in turn secured to the said section II] by suitable means such as the screws "I illustrated.

.An eccentrically mounted pin "I2 is attached to the pulley 62 to impart reciprooatory movement to the pitman M. A second pitman IE is attached to the first mentioned pitman 74 through the medium of a universal joint I8 or other equivalent suitable flexible connection. The opposite end of the pitman 16 is joined to a flange 800i the wall 46 of the hopper carrier through a pivotal connection seen at 32. It is apparent that torque from the motor 54 is imparted to the hopper carrier to vibrate the same. In order to control the actuation of the motor, the switch 42 is utilized. The conductor 84 connects with any suitable conventional electrical current outletto energize the motor however, the switch 40 is interposed in that line to serve its intended function.

The material generally utilized for surface treating of the nature dealt with generally requires the application of heat to render it sufficiently fluid for flow. Accordingly, a heating element 8B is supplied in a housing 88. The said housing 88 extends around the hopper carrier in order to heat the contents of the hopper by conduction. An electrical conductor 99 extends appropriately from the heating element and terminates in the rheostat-switch 38 for control thereof.

A brush 92 which includes a brush holder 94 and bristles is attached rearwardly of the device for reciprocatory movement in order to spread the substance after it has been emitted from the egress portion of the hopper. Brackets 96 and 38 respectively which are attached to the back wall 48 of the hopper carrier are used as hangers for the bifurcated pitman rods I60. One pair of ends of the pitman rods I06 is pivotally attached to the hangers 96 and 98 through the medium of any type of conventional pivot pin, while the other ends of the pitman IUD are pivotally connected to the brush holder element 94. This structure pivotally mounts the brush 92 for pivotal movement on the hopper carrier.

Means for imparting reciprocatory movement to the brush is supplied. A preferred means ineludes a'gear'box I02 having the shaft 55 terminating therein, carrying a pinion. A shaft I04 is supported by a hanger I04 (see Figure 6), which is in turn mounted on the under surface of the section III. At one terminal of the said shaft I94 there is a worm type gear IIlB, see Figure 5, rigidly attached which is enmeshed with the pinion on the terminal of the shaft 56. Accordingly, torque from the motor 54 is imparted through the structure within the gear box to cause rotation of the shaft I64. An eccentric generally indicated at IIl'I is supplied at the opposite end of the shaft I94 for imparting reciprocatory movement to the push rod I 08. At the end of the push rod a bell crank III) is pivotally connected therewith, the crank being pivotally journalled on the rear wall 48 of the said hopper carrier. Secured to an arm II 2 of the said crank by means of a pin and slot connection H4 is an operating bar I I6 which converts the arcuate movement of the crank to rectilinear reciprocation of the brush 92. Since the brush reciprocation mechanism is motor actuated, it will be operative while the hopper vibrating means is operative.

Disposed at the egress portion of the hopper is a valve including a valve plate H8 and a keeper I26 depending therefrom. The valve plate H8 is pivotally attached to the side walls of the hopper through the medium of conventional pivot means A crank I24 having at least two throws I25 and I28 respectively is mounted for rotational movement with the valve plate II8 through the medium of the eyes I30 and I32 respectively. Thesaid eyes are located in the throws I26 and. I28 in order that rotation of the crank I24 will impart pivotal movement to the valve plate II8.

One end of the crank seen at I34 extends substantially perpendicular to the longitudinal ax s of the crank and has a cable I36 attached thereto. Ihis cable is guided by means of a pulley I38 mounted. on the U-shaped support bracket 44 and a second small pulley I40 mounted on the web of the said bracket 44. The cable I 36 terminates on the sheave 42 in order that it may be wound thereon upon rotative movement of the handle 36 as described herein before.

It is quite apparent that rotation of the handle will cause pivotal movement of the valve plate H8 in order to allow more or less substance to be emitted from the hopper.

A pair of arcuate keepers I 42 are pivoted to the end walls of the hopper carrier and the terminal portions thereof contact the flange I20 of the valve plate II8. A spring I44 or other suitable, equivalent resilient urgin means is attached to the sides of the hopper carrier and the arcuate keepers in order to constantly and resiliently urge the valve plate in the valve closing position. Accordingly, rotation of the handle 36 urges the valve plate M8 to the open position against the biasing force of the springs I44, the plate II8 being automatically closed by the potential energy thereof.

Figure 2 discloses that the hopper is simply rested Within the hopper carrier. However, it is contemplated by the present invention to utilize a clamping or latch mechanism of conventional description in order to positively retain the hopper within the hopper carrier, if it is found desirable.

In operation the device is propelled by grasping the handle 36 and moving it on the surface to be coated. The motor 54 is rendered operative, which, through the medium of the belt 60, described pulleys and eccentric arrangement disposed beneath the chassis, causes the hopper carrier to oscillate about the pivot pins 53 as an axis.

Vibratory movement in an oscillatory manner is,

tate the handle 36 which 'isused. for the purpose of motivating the device in its line of travel. By rotating the handle, through the intermediate structure of a pulley and the cable I36 together with the other described structure, the crank I24 is rotated with the valve plate H8, opening the discharge end of the hopper more Or less, against the biasing force of the spring M4.

In instances wherein heat is necessary to maintain the material in the fluent state, the heater 85 is rendered operative; the heater being preferably of the electrically operative type.

For increased beneficial result in spreading the fluent material after it has been deposited in the surface, the brush at the rear of the hopper with respect to the line of travel of the vehicle chassis is reciprocated through the crank and arm structure seen best in Figure 5. This crank, arm and shafting is rendered operative bythe motor 54.

To render the brush effectual or ineiiectual and to remove the brush slightly from contact with the spread material on the surface to be treated, it is only necessary to press downwardly on the handle 36 thereby hingedly operating the sections l and 12 about the hinge pin of the hinge M.

It is apparent that variations may be made without departing from the spirit of the invention.
